I've used them with a bunch of old Unifi and UDM Pro switches and they've always worked fine. As some others have reported they tend to get hotter than you might expect (I don't think this is an issue, I think it has more to do with where in the devices they are) but be You aware of this warmer. especially if you take them out after a few uses. Never had any functional issues with them, they've always been plug and play for me.
